Shortage of oxygen or hypoxia in the tissues for a long time (more than 4 minutes) could cause serious injury eventually leading to fatality. The tissues in our body require oxygen for survival. In acute cases why do we need high flow oxygen therapy rather than use simple oxygen concentrators? Why are Low Flow Oxygen Therapy devices not adequate for acute cases? This condition generally requires support of ventilator to treat patients. CO2 accumulation then prevents them from breathing-in adequate oxygen. Also known as hypercapnic respiratory failure – this condition is caused by patient’s inability to ventilate or breathe-out, resulting in carbon-di-oxide accumulation. a ventilation issue causing low oxygen as well as high levels of carbon dioxide.A patient with such a condition – Hypoxaemia, is generally treated with oxygen therapy. Carbon dioxide levels may be normal or low as the patient is able to breath-out properly. Also known as hypoxaemic respiratory failure – this occurs when the lungs are unable to absorb oxygen adequately, generally due to acute lung diseases that cause fluid or sputum to occupy the alveoli (Smallest sac-like structures of the lung which exchange gases). an oxygenation issue resulting in low oxygen but normal – low levels of carbon dioxide.
In order to apply the appropriate treatment, one needs to determine whether the issue with the patient is poor oxygenation or poor ventilation. Who (What type of patient) needs Oxygen therapy & who needs ventilation? A ventilator not only gives you additional oxygen, it also does the work of your lungs – breathe in & out. Oxygen therapy involves only giving you additional oxygen – your lung still does the activity of taking oxygen-rich air in and breathing carbon-di-oxide rich air out. delivery of oxygen to the tissues.ĭifference between High Flow Oxygen therapy and Ventilator in essence is the following. Oxygenation is only the first part of gas exchange process i.e.
Oxygenation – Ventilation is essential for the gas exchange process i.e oxygen delivery to the lungs and carbon dioxide removal from the lungs. If a patient is unable to do these processes on their own, they may be put on a ventilator, which does it for them. Ventilation – Ventilation is the activity of normal, spontaneous breathing, including the processes of inhalation and exhalation. To understand how an oxygen therapy device is different from a ventilator, we must first understand the difference between Ventilation and Oxygenation. Read on to know more… How is an oxygen therapy device different from a ventilator? What are the indications – Who needs oxygen therapy and who requires Ventilator?.How do they differ in their benefits and risks?.How are these devices different in their capabilities?.How do they work? What are the various components?.What are the various oxygen devices and delivery systems?.You may want to know how oxygen therapy is different from ventilator.Just in case you or your loved one happens to be in the 14% category mentioned above – you may want to know more about oxygen therapy. What you need to know about High Flow Oxygen Therapy The normal oxygen saturation range is 94-100%. It was noticed that some breathless patients had oxygen saturation or SpO2 levels reduced to even 50-60%, by the time they reached Hospital Emergency Room without feeling much else. Governments and people around the world learnt about how COVID19 could lead to lowering of oxygen saturation in the body very silently. March-May 2020 saw a mad scramble for Ventilators in India and all over the globe. Oxygen therapy has become the buzz-word in treatment of COVID19 patients in recent months. How serious is being on oxygen therapy? Oxygen Therapy vs Ventilation in COVID19 Oxygen concentrator is Low Flow Oxygen Therapy and what hospitals are using to treat acute patients, is High Flow Oxygen therapy.”Įveryone else wondered, what exactly was the difference between Ventilator and Oxygen therapy – High Flow or Low Flow?!Įveryone knows being on ventilator is serious. My Mother has been using Oxygen concentrator for nearly 2 years now.” Another knowledgeable member commented, “It’s not the same. A third member chimed in, saying, “Oh! that is not too bad. Another member enquired if she was on ventilator? The first member replied she was actually on ‘Oxygen Therapy’. “My neighbour has been detected Covid-positive and admitted to nearby hospital”, reported a WhatsApp group member a few days back.
